8. Connecting Overload to a Contactor

Overloads can easily be attached to a contactor by:

(1) First disconnect all electrical power leading to the contactor.

(2) Using a Phillips head screwdriver, unscrew the five terminal screws on the right of the

contactor. These are labeled (2T1, 4T2, 6T3, 14NO and A2).

(3) Carefully place the overload unit so the five pins align with the contactor as shown below.

(4) Press the overload into the contactor until a “snap” is heard.

(5) Tighten the five terminal screws (2T1, 4T2, 6T3, 14NO and A2).

(6) Verify the overload control options (See Section 7).

9. Connecting Contactor to Controller and Loads

This section displays several methods of connection the Contactor Panel to Controllers, Power Sources

and Loads.
